Application led July 10,

To all @L1/mm may concern.'

.Be it known that I, Jnarrs F. Srnnr'r, a citizen of the United States,residing at Baltimore, in the county of Baltimore and State of Maryland,have invented certain new and useful Improvements in Dust Shields, ofwhich the following is a speciication.

rlhis invention relates to a dust shield for covering and protectingportieres, curtains or the like.

An important object of the invention is the provision of a portire dustshield having a sheet, cloth or other similar protectm ing meanssuspended therefrom, and which is supported from a door or window casingin such manner as to cover and protect the portires or curtains thereonfrom dust or other substance which might injure the portieres orcurtains.

A further object is the provision of a dust shield of the abovedescribed character formed of different sections so as to permit its useupon various sized window or door casings, and which can be folded intoa relatively small and compact size for convenience in handling.

Cther objects and advantages will be apparent during the course of thefollowing detailed description. ln the accompanying drawings forming apart of this specication and in which like reference charactersdesignate like parts throughout the same.

Figure l is a lfront elevation of the portiere dust shield supportedfrom a window casing, and covering the portire thereon, to protect thesame from dust or other foreign substance.

Figure 2 is a side elevation of the dust shield supporting means in afolded position.

Figure 3 is a fragmentary sectional view of a portion of the device.

Figure 4 is an end elevation of the dust shield supporting means, whenin a folded position.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the letter A designates a windowor door casing having' the curtain or portiere B suspended therefrom inany suitable manner. The supporting bar C is so arranged and suspendedfrom the casing A by hooks D or other approved means in such manner thata dust shield E of any flexible material such as a sheet,

cheese cloth or the like is supported therefrom'by clamps F to cover andprotect the curtains or portires from dust or other foreign substance.

The supporting bar C is preferably constructed of two or more foldablesections l() and 1l, which are foldably connected by a hinge l2 or thelike. The leaves of the hinge l2 are preferably countersunk in the facesof the sections l0 and ll in such manner that the abutting faces of thesections l0 and ll will lit closely together when the supporting bar isin a folded position. The section lO of the supporting bar C is providedupon an end thereof with a projection 13 adapted to ride upon anextendinn' edo'e 14 of the clip l5 which is securely facstenl to the endof the section 1l, and adapted to seat itself within an tension 14 insuch manner as to lock the sections of the su )porting bar in a foldedpositlon, as clearly shown in Figure 2 of the drawings.

When the supporting bar C is in an eX tended position and it is desiredto use the same upon a relatively wide window or door. it is supportedupon or4 from the saine by the hooks D which are upon the upper surfacethereof and engaged therein in any suitable manner such as by screwthreads or the like. lt is preferred that the hooked ends 2() beprovided with the pointed extensions 21 for firmly biting into thewindow casing and effectively support the device therefrom.

The clamps F while firmly and securely holding the dust shield E willyet permit its removal therefrom by merely exerting a pull upon the dustshield E. lt is preferably of the type employing' jaws 23 and 2&1; whichhave their gripping ends forced tight together by spiral springs 25, insuch main ner as to securely grip the dust shield or other article whichis to be suspended from the support-ing bar C. They are arranged upon alongitudinal edge of the supporting bar C in such manner that the dustcloth E is evenly suspended therefrom. rlhey are preferably individuallyclamped to the supporting bar C by a wire band 26 extending through thespiral spring 25, and having their projecting ends 27 and 28 threadedlaterally through apertures in the bar C and twisted together as at 29to securely fasten the clamp to the supporting bar. The twist E29 ispreferably folded over and seated withaperture in 'the er;- 1

in a recess 30 in an edge of the bar C. The recess 30 may be iilled withsealing Wax, or

the like to cover up the end 29 in order that the portires when it Willnot catch upon using the device.

It is to be noted that either of the sections l() or ll form inthem-selves a complete means for suspending the dust kcloth E over arelatively narrow door Wayv or Window casing.

The hook D :andclamp F aresoarranged upoirthe sections lO andll of the.supporting bar C that they Will not interfere with folding of thediiiferentysections upon each other in anyway.

The usual procedure is first to evenly arrange the dust shield upon thesupporting bar C by the clamps F, and then to lift it bodily and Supportit from the Window casing A by the hooks D as is clearly` shown inFigure l of the4 drawing.

Itis to be understood that the formof my inventioinherewith shownanddescribed is to be taken asalpreferredfexample of the same and thatvarious changes in theV shape, size and arrangement-ofparts may be madeWithout departing iroin the spirit ofthe inf l claim: y
